HESI Fundamentals Practice Questions
1. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 400 mL/hr
- B. 200 mL/hr
- C. 300 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.
2. A nurse is teaching the parents of a child with a diagnosis of epilepsy about seizure precautions. What should the nurse include in the teaching?
- A. Keep a diary of seizure activity
- B. Administer antiepileptic medication only when a seizure occurs
- C. Restrict the child's activities to prevent seizures
- D. Teach seizure first aid to family members
Correct answer: D
Rationale: Teaching seizure first aid to family members is essential as it empowers them to respond effectively during a seizure. Keeping a diary of seizure activity is important for tracking patterns and triggers but is not directly related to immediate safety. Administering antiepileptic medication only when a seizure occurs is not recommended as medications should be administered as prescribed by healthcare providers. Restricting the child's activities to prevent seizures is not appropriate as children with epilepsy should be encouraged to lead active lives while taking necessary precautions.
3. At a support meeting of parents of a teenager with polysubstance dependency, a parent states, 'Each time my son tries to quit taking drugs, he gets so depressed that I'm afraid he will commit suicide.' The nurse's response should be based on which information?
- A. Addiction is a chronic, incurable disease
- B. Tolerance to the effects of drugs causes feelings of depression
- C. Feelings of depression frequently lead to drug abuse and addiction
- D. Careful monitoring should be provided during withdrawal from the drugs
Correct answer: D
Rationale: The priority is to teach the parents that their son will need monitoring and support during withdrawal to ensure that he does not attempt suicide. Option A is incorrect because addiction can be managed and treated effectively with appropriate interventions. Option B is incorrect as tolerance to drugs causing depression is not the primary concern in this scenario. Option C is incorrect as while depression can be a risk factor for drug abuse, in this case, the focus is on the son's safety during withdrawal.
4. When taking a health history of a client admitted with acute pancreatitis, which client complaint should be expected?
- A. A low-grade fever and left lower abdominal pain
- B. Severe headache and sweating all the time
- C. Severe mid-epigastric pain after ingesting a heavy meal
- D. Dull, continuous, right lower quadrant pain and nausea
Correct answer: C
Rationale: The correct answer is C: 'Severe mid-epigastric pain after ingesting a heavy meal.' This symptom is characteristic of acute pancreatitis due to inflammation of the pancreas, which often presents with severe pain in the mid-epigastric region that may worsen after eating. Choices A, B, and D describe symptoms that are not typically associated with acute pancreatitis. A low-grade fever and left lower abdominal pain (Choice A) may be more indicative of other conditions like diverticulitis. Severe headache and sweating (Choice B) are commonly seen in conditions like migraines or infections. Dull, continuous, right lower quadrant pain and nausea (Choice D) could be suggestive of appendicitis rather than acute pancreatitis.
5. When evaluating the effectiveness of a client's nursing care, the nurse first reviews the expected outcomes identified in the plan of care. What action should the nurse take next?
- A. Determine if the expected outcomes were realistic
- B. Obtain current client data to compare with expected outcomes
- C. Modify the nursing interventions to achieve the client's goals
- D. Review related professional standards of care
Correct answer: B
Rationale: After reviewing the expected outcomes in the plan of care, the nurse should obtain current client data to compare with these outcomes. This step is crucial in determining the effectiveness of the care provided. Choice A is incorrect because determining the realism of expected outcomes comes after assessing current client data. Choice C is incorrect as modifying nursing interventions should be based on the data comparison rather than done immediately after reviewing expected outcomes. Choice D is also incorrect as reviewing professional standards of care is important but not the immediate next step in evaluating care effectiveness.
